Answer:
2x-y=2
2x-2=y-------(1)
3x-4y=(-2)
3x-4(2x-2)=(-2)
3x-8x8=(-2)
(-5x)=(-2)-8
x=(-10)/(-5)=2
y=2(2)-2=4-2=2

Answer:
Using substitution method we will find value of x from eq ---> 2x-y =2
Therefore x =2+y/2
Put this value of x in 2nd eq - - - > 3x-4y=2
From here we got the Value of y=2/5
Step-by-step explanation:
Hope it helps
